  • the intermediate communication device is a communication device located at a contact connecting these different sub-networks
  • the intermediate communication device The route establishing means establishes a route with the transmission destination communication device when the intermediate communication device receives a packet addressed to the transmission destination communication device from the transmission source communication device.
  • the proxy response means proxy-reply to the transmission source communication device on behalf of the transmission destination communication device when the path is established by the route establishment means. According to such a configuration, it is possible to reduce the amount of buffers that the intermediate communication device should have and to suppress the occurrence of unnecessary communication.

Abstract

Le problème décrit par la présente invention est de réduire la capacité de mémoire tampon nécessaire pour une mémoire, et également de supprimer la survenue d'une communication inutile. La solution selon la présente invention concerne un système de réseau ayant au moins un dispositif de communication (10) au niveau de la source de transmission, un dispositif de communication (60) au niveau de la destination de transmission, et un dispositif de communication intermédiaire (20) disposé entre le dispositif de communication au niveau de la source de transmission et le dispositif de communication au niveau de la destination de transmission, le dispositif de communication intermédiaire ayant une fonction pour connecter ensemble des sous-réseaux qui construisent une route de communication avec des protocoles de construction de route mutuellement indépendants, le dispositif de communication intermédiaire (20) étant caractérisé en ce qu'il a un moyen d'établissement de route (unité de commande (22)) pour établir une route vers le dispositif de communication (60) au niveau de la destination de transmission lorsqu'un paquet adressé au dispositif de communication (60) au niveau de la destination de transmission est reçu à partir du dispositif de communication (10) au niveau de la source de transmission, et un moyen de réponse de mandataire (unité de commande (22)) pour répondre au dispositif de communication (10) au niveau de la source de transmission comme mandataire pour le dispositif de communication (60) au niveau de la destination de transmission lorsque la route est établie par le moyen d'établissement de route.
